To make yogurt mayonnaise, place yogurt, mayonnaise and milk in a bowl. Whisk in mustard, oil, vinegar and lemon juice. Add sweet paprika and salt and pepper to taste. Be generous with the seasonings. Fold in herbs. Pour dressing over salad. Chill, covered, 1 hour. Crumble pumpernickel bread, if using, over salad just before serving.
